JOHN CLINTON RIEGEL, OF POTTSVILLE, PENNSYLVANIA.

VARIABLE-SPEED MECHANISM FOR MOTOR-VEHICLES.

Be it known that I, JOHN C. 'liizonn, a citizen of the United States,residin at loltsville, in the county of Schuylkill and State ofPennsylvania, have invented a new and useful Varia re -Speed Mechanismfor MctouVehicles, of which the following is a specification. 1 I

This invention has reference to improvements in variable speed mechanismfor metcr vehicles. o'r vvhereyhr it is desired to impartvariable speednto a driven member from a; driving member Theobjcct of the pres-chiinvention is to provide a mechanism of this character which is simple inconstruction, cheaply manufactured, readily accessible, compact,durable, etlicient and reliable in operation and always under perfectcontrol.

The present invention provides means for obtaining variation in speedbetween a driving (le ice and a driven device, which variation may rangefrom rest or zero motion to full speed in either direction, and inaddition thereto means are provided wherc varying or changing of theratio ct speed driven device, thus securing a proper proportion ofavailable power at times when the resistance or load on the drivendevice is varied. In many power transmission means, of which that of amotor vehicle is a pertinent example, starting or even marked.variations in load are liable to produce jars'and shocks destructive tothe vehicle machinery, or even parts of the vehicle itself, but in thepresent invention all such jars and shocks are eliminated and there isprovided an elastic transmission whereby the vehicle may be started fromrest so gradually that no In motor vehicles particularly it is cus-.tomary to provide manually operable means for controlling the operationof the mechvery simple and yet "effective interlocking mechanism for theusual brake and clutch operating edals, which precludes the possibilityof t e accidental engagement of the power and the brake simultaneously,as well as preventing engagement of the reversing Specification ofLetters Patent.

is adapted to be wholly incased" so that the running parts may becontinually immersed in oilfor thoroughlubrication at all times,

this not only increasing the eificiency and durability of the inclosedparts, but pro tecting. them against the effect of foreign substances,such as dust and dirt, and besides rendering the entire mechanismpractically noiseless.

Vhile the present invention is not of necessity confined to use on motorvehicles, it is particularly adapted to such use, wherefore in thefollowing description it will be considered that the invent-ionis'applied to a motor vehicle, thus avoiding complexity of description,without, however, confining the use of the invention to the particularassociations described.

The invention will be best understood from a considerationof.the'fcl10w'ing detailed description, taken in connection with theaccompanying drawings forming a part of this specification, with theunderstanding, however, that the embodiment illustrated, thoughpractical, is by no means-the only embodiment which the invention mayassume, wherefore the invention .is not confined to any strictconformity with the showing of. the drawings, but may be changed andmodified in various particulars, so long as such changes andmodifications mark no material departure from the salient features ofthe invention.

. Carried by the web ll is a cylindrical shell or support 23 carryingtwo spaced rings Qt, Q4, and to these rings may be connected conductors:25 coming from respective terminals of the coils 14. If each coil hasits terminals connected to the respective'rings 24-, then the coils arewound accordingly both as vto quantity and gage of wire. It is quitefeasible to connect .the coils up in series and simply carry the twoends of the series by appropriate conductors 25 to the two collectingrings 2d. The cylindrical shelf 23 may be made of :insulating materialor the rings 21 may be separately insulated therefrom it the shelf bemade of metal. Both of these arrangements are inditterently employed byelectrical constructors.

The casing 5 does not terminate coincident with the end of the shaft 3,but there expands radially until of greater diameter than the rim 12,and is then continued in the direction est-the length of the axis of theshaft 3 to form an inclosingmember 26 for the field which may beconsidered as typified by the ring 12, but the axial extent of thecasing member 26 is only suiilcient to partially inclose the field forthe member 26 is met by a matching member 27 and both of these membersmay have lugs 28 formed thereon whereby fastening bolts may be used toconnect the two casing members 26 and 27 togather. The casing 26 is ofsufiicient axial length to inclose the field and certain. parts and isthen contracted toward the axis of the shaft 3 if the latter beconsidered as prolonged, and then the easing is provided with anelongated axially extended portion 28" of a suitable length to inclosecertain mechanisms to be described.

The several casings or parts of casings referred to are usually ofcylindrical form in.

cross section, but these casings are custom-- arily made in twolongitudinal halves or parts with appropriate flanges at the meetingedges to admit of the securing of the two parts together by belts orscrews, and their ready separation for the assemblage of the inclosedparts or the cleansing of the interior of the casing or inspection orrepairs as may be needed. Moreover, the casing 26 is provided withpassages 29, 3O usually located on what constitutes the top of thecasing when in use and these passages are normally closed by a coverplate 31. Of course, it wilhbe understood that suitable provision is zladed'ior rendering all the joints sufficiently tight to resist leakageof lubricant, for after the are assembled the casing may be sup liedvith a suiiiciently large amount ott' lu r nthto in most part immersethe )late 3:? with an out-wardl i extended radial flange into which thestuds 31 are screwed. At. the end of the sleeve 33 remote from theflange 35 is an outwardly extended radial web 36 terminatinq in' aperipheral axially extended flange 31' having its outer surface close tothe inner wall of the corresponding portion of the casing extension 28'.Meeting the free edge of the flange 37 is a similar flange 38 carried atthe other end by a radial web 39 on one end of a sleeve 40 corresprmdingto the sleeve 33 and in turn at the end remote trout the flange 39 pro-,vided with another radially extended web 41 baring a peripheral axiallyexpanded flange 42 directed away from the web The flange 35 and web 36form between them about the sleeve 33 an annular groove or channel inwhich is seated an anti-friction bearing 4-3 of known type and henceneeding no hilth'uliil' dcsi'iription, and this hearing is in turncarried by a web 44 formed on the inner all of the casing extension 28at an appropriate point. The webs 39 and 4-1 at epposite ends of thesleeve 40 form tcgetl'ier with said sleeve a channel for ananti-friction hearing is similar to the bearing 43, and this hearing isalso carried by a web 4 Z-formed on the inner wall oi. the casingextension 28 at an appropriatepoint. The two flanges 37 and 38 arecoupled together by bolts or other fastening devices 47 shown in Fig (i,the flanges 37 and 38 having appropriate cars 48 for the passage of thebolts or screws 47. The two sleeves 33 and 4.0 are therefore connectedtogether as though made in one piece, but they are divided for thepurpose of permittingthe assembling of parts interior to the webs andflanges carried by the sleeves.

Mounted interior to the sleeve 83 is an other sleeve 49 and within thespace defined between the webs 3G and 39 this sleeve has an axiallyextended web 50 which at appropriate points near its peripher Y isformed with axially projecting bosses 51 each carrying a stud pin 52screwed into the boss and at the other end formed with a laterallyexpanded head 53. Each pin between the boss 51 and its head 53 hasmounted thereon a pinion 54-. Within the sleeve 40 there'is anothersleeveso having at the end interior to the chambiw' bctween the webs 36and 39 and adjacent" tobthe latter an axially ex tended web 56, whichmay be similar in all respects to the web 50 with its bosses and the web56 carries headed pins 57 interspersing with the pins 552.

The shaft is continued tl'irough the sleeve 49 and enters the spacedefined between the webs 50 and 56 and terminates at a point somewhatshort of the n l-point; between these two webs, the shaft 1";- n thecorresponding end of the sleeve terminus of the shaft being square Gatedat 58.

The sleeve is elongated with rcf-3uce to the length of the sleeve 49 andis. ersed by a shaft 59 to which reference, will hereinafte he made,this shaft extending nd (i beyond the web 56 toward the squared e of theshaft 15, and is also there square as indicated at 60. Mounted on thesquared end 58 of the shaft 15 is a gear wheel (31 and mounted on thesquared end 60 of the shaft 59 is a gear wheel 62 similar to the gearw'ieel 61. The adjacent ends of the squared portions 58 and 60 of theshafts 1:3 and 59 are separated by z spacer \Vhich may also enterbetween. the gear wheels 63, and 62. These gear wheels are spaced apartt their toothed peripheries a SHl'ilCllTi) disance to permit engagementof the pinions L with the gear wheel (52 but not with the 1 ,ar wheel61, while other pinions 64L engage he gear wheel 61. The pnions 5%: and(3. -e of such length that they overlap and where overlapping they areso related as to inesln so that all the pinions 5% and 64- are in meshone with the other, while only the pinions 54 mesh with the gear wheel62 and the pn'nons 6 iwith the gear wheel 6L and these oinions and gearwheels constitute the only connection\het'wecn the shaft 1:") and theshaft T he casing" 28 is siiil'iciently elongated for theaccoininodatiqnjof other structures than those alreai'ly" described andadjacent the end remote from the gearing just described i casing isformed with an inwardl dielfi rected radial web carrying an aniiar'otioni hearing 66 like the harings i3 and 42 5, and this hearing supportsthe correspond ing end of the sleeve T which is su'liiciently elongatedto reach the hea ing 66.

25, Mounted upon the sleeve between the two. groups of disks is anothersleeve 83 of suffic ent internal diameter to house a spring 84 between;the sleeve 83 and the sleeve 55- and one end of the sleeve83-is-provided with 9- an inturned flange 85 Whichmay bear upon theexterior of thesleeve 55'and form an abutment for one end ofthe spring84,;wh1le the other end of the spring abuts against a nut 86 in the formof an internally threaded. 35. ring entering the end of the sleeve 83remote from the flange 85 and engaging appropriately placed screwthreads on the sleeve 55. 'I he nut 86 is adjacent that group of diskswithin theflange 76, which latter, because 0, the web 7 5 carrying it ismade permanently fastto the casin 28, may be called the fixed flange,While t ie other flange 42 may be termed a rotatable flange because itis carried by the web 41 in turn-carried by the sleeve 45, 40 which hasthe web 39provided with the flange 38 made fast to the flange 37, andthis latter by. the web 36 and sleeve 33 is made fast to the disk 32which in turn is fast to,

the field ritn- 12 secured to the main drive The sleeve 83 is externallyscrew threaded for adistance from the end provided with the flange85,-while the remainder of the sleeve-is smooth and the end remote fromthe 55 flange 85 is provided'with an out-turned ra-- dial "flan" e 87.Mounted on the threaded part ofthe sleeve 83 isan internally threadedrin 88' havingone end'thickened to form a shou der 89, and between thisshoulder'and Go the flange 87 the/smooth part of the sleeve 83 carriesacollar 90 of-less width than the distance between-the shoulder 88 andflange 87-toaccommodate balls 91; to form a thrust bearing, while theedges ofthe collarareexw intended overlapping relation to the shoulder88 and flange 87, as indicated at 92 and 93, respectively, the extension93 serving as a retainer for the balls-91.

By reference to Fig. 5 it will be seen that the collar 90 has trunnions94; on diametrically opposite sides entering cars 95 at the ends of ayoke 96 connecting the ears in overriding relation to the collar, andthis'yoke is also provided with trunnions 97, 98, respectively,extending through bearing sleeves 99 carried by the appropriate part ofthe dis ing 28, these sleeves 99 being of suflicient length to engageinner shoulders 1-00 at those ends of the trunnions 97 and 98 wherejoining the yoke 96. The trunnion 97 simply serves as a supportingmember while the for an appropriate distance beyond the correspondlngside of the caslng 28 and'constltutes an actuating member for the yoke,as

trunnion 98 is of suflicient length to extend will hereinafter appear.The sleeves 99 not only serve as elongated bearings for the trunnionsbut avoid leakage of lubricant which is liberally supplied to thecasingto practically immerse the moving parts within the casing. 1

The normal tendency of the spring 84 is to force the flange 85 intoengagement with the outermost disk 77 of the group carried by therotatable flange 42 and all thrust ofthe springthrough the sleeve 83upon the collar is transmitted through the ball bearings 91. \Vhen,however, it is desired to utilize the clutch carried by the fixed flange76 it is necessary to compress th spring 84 against its normal tendencyand the force necessary to bring this about is exerted through the ballbearings 91. In

either case, therefore; the thrust of the 9 spring is so far as the8ollar90 is concerned, exerted through the ball bearings'91. While thebearings 91 are referred to as ball bearingsandotheranti-frictionbearings through the-structure are indicated asball bearings, it will be understood that any appropriate form ofanti-friction bearings may be em-,

ployed where it is desirable to use antifrietion bearings. 1 The shaft59 is supported within the sleeve 55 at appropriate points, preferablynear the ends, by sleeves 100/ of appropriate material designed toreduce friction and at-the same time resist the wear The shaft 15 withinthe sleeve 49 and within the counterbore 9 In order to supply the eneizing current for the coils i i and For other purposes, there is providedmotor rotor 10% which may receive pow mover 2 anti may he'eitl shaft 3or throu ing or gear tor generator current t motor it is aclr motor forthe p tion, 'Lie O'L'LJ'UUI'I when opereti by Yerying the col oi. theprime motor within its iillllll lGai ige of. variation, as themagnetizing iOlCE the electromagiiet composed of 'th ls 1e will be direcly proportionate Hi) of i may 1 ti on 11 nerzitor J be varied the speedor the 1 will, the automatic ferrecl to acting '21 c [LlLiOil in outputthe variation in see upon the Va e motor, but Wii s Variation in speed.0'' s a more pronounced variation in the speed of the vehicle than inLofore so that with such limited range of s motor the speed o. fromabsolute verse.

bolts from strain. The running gear of the vehicle is quite flexible asis customary, and this flexibility is permitted with respect to thedriving gear by the universal joint (57 and the spherical support 69 inthe spherical holding means 70 and T1.

The driving movement thus described relates to the forward drive of thevehicle.

Suppose, now, it be desirable to back the vehicle, then the clutchsleeve 83 is moved in a direction to further compress the spring 8 1 andbring the flange 87 into engagement with the outermost one of the disks77 in the fixed flange or housing 76. Those disks 80 directly connectedwith the flange or to the pinions 5 1, although these pinions, as

well as the pinions 64, are held against orbital movement. The rotativemovement of the interconnected pinions and the gear Wheel 61 impartsrotative movement to the gear Wheel 62, and this in turn impartsrotative movement to the shaft 59, but in a direction the opposite tothat first described, so that the'dircction of movement of thevehicle isreversed, When the clutch sleeve 83 is in the intermediate positionbetween the two series of clutch disks, then the shaft 59 is not coupledto the prime mover at all and the vehicle will either be at rest or maytravel independently. In a motor vehicle it is necessary that thesedifferentadjustments be brought about by means accessible to theoperator when seated in the vehicle, so that following the ordinarypractice, a pedal arrangement is provided, but in order to accommodatesuch pedal control to features of the present invention, it becomesnecessary to arrange the pedal control in a different manner thanheretofore. The arranger'nent of pedals is illustrated in Fig. 5 and inFigs. 10 to 18. Two angle pedals 11 1,1115 are mounted upon thatportionof the trunnion or shaft 98 outside the casing, 28, eachpedalbeing provided with an appropriate foot piece 116 for theapplication The pedal 11 i is provided with a hub 117 at the end remotefrom the foot plate 116' and formed on this hub is a segmental extensionor plate 118 extending therefrom at an angle to the length of the mainportion of the pedal 114, wh'ch latter is made fast to the shaftextension 98 to cause actuation of the latter by the proper operation ofthe pedal 11st. The other pedal 115 is provided with an elongated hub119 and also with a segmental plate 120 extending from the hub at anangle to the main portion of the pedal 115. The hub 11!) is free to moveon the shaft or trunnion 9S and both of the hubs may be held to theshaft 98 by a nut 121 applied to a reduced threaded extension of theshaft.

One corner of the plate 120 is pivot-ally connected to one end of a'linkand the other end of this link is pivoted to one end i of another link1223, the farther end of which last named link is pivoted to a stud 12 1car ried by a suitable projection from the casing 28. it the junctionpoint of the two links 122 and 123 there is pivoted one end of anotherlink 1% terminziting at the farther end in an elongated eye 127 providedwith an elongated slot 128 in which engages a pin 129 on the lever llt.

The two segmental plates 118 and 120 have one edge lodged in appropriategrooves in a guide member 130 carried by the casing 28, and this guidemember may be made up of an appropriate number of plates held to theguide member by belts or other fastening devices 131. The guide member130 has an internirdiate portion 132 spacing. the so mental plates 11Sand 120, and through this intermediate portion is a passage 133 in whichis lodged a ball 134:. This ball is designed to operate as a heatingstop member and may therefore be either in the forrp of a ball or sphereor in the form of a pin or cylinder, or be of any suitable shape for thepurpose. That face of the plate 118 adjacent to the intermediate portion132 of the guide member 130 is provided with an elongated recess and theplate 120'on that face toward the intermediate member 132 is providedwith a recess 13G agreeable to the size of the ball or stop member 134.The thickness of the intermediate portion 132 and the thickness of thestop member 13 1 are so related that the stop member will project intoone or the other of the recesses 135 or 136, the thickness of the stopmember 134: being greater than that of tli i intermediate-member 132 bythe depth of the recess 135 or 136, each recess being of the same depth.If the plates 118 and 120 be so positioned that the recesses areopposite the; stop 11iembci 184, then one or the other of the platesmaybc moved to carry its recess out of coincidence with the stop member13 1-, but the other plate will remain in a locked position by said stopmember, except that the plate 118 has an extent of movement independentof the stop member agreeable to the length of the recess 135. By thisarrangement certain movements are permitted for each pedal and duringcertain positions of each pedal the other pedal is locked agai st amovement sufficient to permit the ictuation' 01 certain, 01 the devicescontrolled av the pedal.

The first part of this movement of the clutch lever is quiterapid,

and then rapidly diminishes, so that the further movement of the brakelever to the position Where the brakes are on maintains the clutch leverin the neutral position, the lengtl'i of the recess admitting of thismovement and preventing the ball 13st from interfering with the propermovement of the brake pedal. The elongated slot 128 and the elongatedrecess 135 permit certain angular movement out either of the pedalsindependently of the other. For instance, the clutch pedal may be heldin the neutral position while the brake pedal is allowed to move torelease position and with the. brake pedal in this position the clutchpedal may be moved to its forward clutch engaging position and againback to the neutral position independently of the brake pedal.
